Autoethnography Essay Ysabel Anne Aluquin (z5146099) According to the Oxford Dictionary, selfie can be defined as “a photograph that one has taken of oneself” (selfie, 2017). However, according to Rettberg, selfies are so much more than just a photograph on the Internet, they are a form of digital self-representation (Rettberg, 2014). I still remember the very first selfie I took, with the back camera of an old Nokia phone. This was before the invention of the front-facing camera and in comparison

should be in the right place as well. Filtration is important to clean the water in the tank. All types of aquarium have this equipment. Then, you need to choose the best filter for this. The filter is the essential equipment in an aquarium and has different sizes. So, you have to consider where it should be put on. You can put your filter in several locations around your

industries and areas of study; however this analysis is challenging because aerosol particles can be difficult to collect.1 Aerosol particles can be collected onto a substrate and then analysed. The collection surface can be a porous medium such as a filter operating at a low flow rate whereby some or all of the particles suspended in the aerosol flow are retained. In many applications particles from the gas flow are extracted by an externally applied force e.g. in a centrifuge or electrostatic precipitator

Version 2: 5 fish, mean fish, dead fish, no fish! I opened the black hatch on the lid of the fish tank. Turning open the lid of the plastic container, I reached inside and took out a pinch of the musty-smelling fish food flakes. I sprinkled the flakes over the water in the fish tank and watched as the 5 fish swam up, gulping up the thin copper, crimson, and mahogany colored flakes. I watched until the fish swam away, finished with their meal. I then closed the hatch, put away and closed the jar

Air Filters | Air Conditioning Service Arlington, TX No homeowner is going to complain about having cleaner air in their home. This is especially true after the EPA revealed that the air in many U.S. homes is more polluted than the outdoor air. Receiving cleaner air doesn't need to be difficult, or come with an excessive cost. Your HVAC system's air filter can assist you in achieving cleaner air, if you use the right type. Your Minuteman Heating & AC technician can assist you in selecting the right

such as energy detection, matched filter and so on [1 6 7]. Different techniques serve different purpose based on their advantages and disadvantages. In this paper, the author suggests an approach of dynamic threshold to increase the probability detection of spectrum sensing. Spectrum sensing using energy detection, matched filter detectors based on fixed threshold and dynamic threshold are simulated using MATLAB. The performance of energy detection, matched filter detector is compared by plotting

choose from three different filters, F1, F2, and F3. F1 is the standard filter with two layers consisting of an outer particulate filter and an internal active carbon element. The outer layer traps particulates down to 1 micron. The activated carbon layer is effective towards fumes and odors. Testing shows that this filter is 99.9 percent effective. The F2 is a HEPA filter with 2 layers of particulate filtration. This particular filter does not have an activated carbon filter however. This one promotes

they cannot look at things that can be harmful to them. Of course the supporters of the First Amendment opposed this law. They opposed this law because the filtering systems could filter out things that could be educational, or used for health research. There will always be problems with filters; they will either filter too much or not enough material. This is especially true since,

on the state of pollution of the air and its dimensions. This is to be taken into account in the choice of the device and its use. Air purifiers will help you breath clean air, year-round. Initially, air purifiers were found only in industries to filter and remove toxic residues. If the quality of the air is not excellent, the body must fight to eliminate this pollution and the most fragile people often develop respiratory diseases (allergies, asthma, cancers, etc.) whose source is certainly partly
